Make a small spreadsheet easier to use and keep a clear record of what changed. I trim extra spaces, remove exact duplicate records when requested, standardize unambiguous dates and improve readability. Missing or unclear entries stay visible for your review.

An XLSX workbook with original data, cleaned data and audit notes.

A cleaned CSV.

A summary of retained and removed rows, changes made and unresolved entries.

$15 covers one CSV file or one data worksheet from an XLSX file, up to 100 data rows and 10 columns. Delivery is 3 days after complete files and cleanup rules, with 1 revision within the original dataset and agreed scope.

Send the source, worksheet name, duplicate-removal preference, intended date format and known locale, and any fields whose spacing must stay unchanged. I apply the agreed rules, account for every source record and hand over the files with a concise change log.

Exact duplicate checks compare all original fields and retain the first occurrence. Similar records, ambiguous dates and text quantities remain for your clarification.

Supply authorized data with sensitive identifiers removed. Formulas, macros, dashboards, research and combining datasets require separate scope review. Missing values are not guessed.

The linked fictional study accounts for all 14 source records: 12 retained and 2 exact duplicates removed.
